Berlin, Germany
Summary
👤
Senior🎓
Top SchoolPeter Leonov is a Senior Software Engineer based in Berlin with 17+ years building high-performance web platforms, cloud-native systems, and developer experience tooling. He combines deep full-stack expertise—from edge and server-side JavaScript to compilers and observability—with hands-on experience at companies like Shopify, Zalando, Cloudflare and ClickHouse. Known for improving scalability and developer productivity, he has driven large projects such as Shopify’s Spin CDE and reliability efforts for high-traffic e-commerce and CDN services. An active open-source maintainer, his projects include an nginx JavaScript routing module, a JS port of the Ruby 2.0 parser, and tooling for semi-automated unit testing, reflecting a strong interest in language tooling and platform extensibility. He pairs rigorous engineering (distributed observability, A/B testing, micro-caching) with pragmatic product focus, and is equally comfortable shipping low-level performance wins and developer-facing systems. Outside work he balances parenthood with continuous learning and persistent contributions to OSS that bridge compilers, runtime, and infra.
